Hi Mischa,
That is a tough situation. I think your grandfather needs to find a good internist and cardiologist where he is going. His passing out spell was likely
vasovagalFainting since it sounds like he was having blood drawn at the time he passed out, but this should be evaluated by his doctor. Regarding
cardiacCardiac catheterization
Cardiac tamponade
Left heart ventricular angiography causes of passing out, if his heart function is less than 35%, he may qualify for a
defibrillatorImplantable cardioverter-defibrillator .
Regardig his safety driving, I am afraid I cannot assess this his driving safety without meeting him. That just re emphasizes the importance of finding a good doctor.
Sorry I cannot be of more help. Good luck.
They said an MRI is the only way to know for sure, but they didn't think it was necessary yet. What? No one seems to think it is urgent.
Well, I supposed I should just click my heels and see if it all would just go away. hee hee.
